摘要： In one aspect, the disclosure includes an apparatus comprising a processor configured to function as a merge point (MP) in a point to multi-point (P2MP) backup label switching path (LSP) for a primary LSP, receive P2MP backup LSP information originating from a protected node, wherein the P2MP backup LSP information comprises the identity of a point of local repair (PLR), determine a backup label switching router (LSR), and send a message with the identity of the backup LSR to an upstream node.
摘要翻译：一方面，本发明包括一种装置，包括被配置为在主LSP的多点（P2MP）备用标签交换路径（LSP）的点到点的合并点（MP）的功能的处理器，接收P2MP备份LSP信息来自受保护节点，其中P2MP备份LSP信息包括本地修复点（PLR）的标识，确定备份标签交换路由器（LSR），并将具有备用LSR标识的消息发送到上游节点。

摘要： An apparatus comprising a backup node coupled to an ingress node of a point-to-multipoint (P2MP) label switched path (LSP) and to a plurality of next-hop nodes of the ingress node of the P2MP LSP via a backup tree, wherein the backup node and the ingress node are both coupled to an external node, and wherein the backup node is configured to ensure data delivery in the P2MP LSP when the ingress node fails. Included is a network component comprising at least one processor configured to implement a method comprising detecting a failure in an ingress node of a P2MP LSP, receiving a data packet destined for the ingress node and to be transported by the P2MP LSP from a provider node when the ingress node fails, and transmitting the data packet on a backup tree that merges with the P2MP LSP prior to reaching an egress node.
摘要翻译：一种装置，包括经由备份树耦合到点对多点（P2MP）标签交换路径（LSP）的入口节点和P2MP LSP的入节点的多个下一跳节点的备份节点，其中，所述备份节点和所述入口节点都耦合到外部节点，并且其中所述备份节点被配置为当所述入口节点发生故障时，确保所述P2MP LSP中的数据传送。包括的网络组件包括至少一个处理器，其被配置为实现一种方法，该方法包括：检测P2MP LSP的入口节点中的故障，接收目的地为入口节点的数据分组并且由P2MP LSP从提供商节点传送，入口节点发生故障，并在到达出口节点之前将数据包发送到与P2MP LSP合并的备份树上。
